YARN GUIDE AND CLEARER.

SPECIFICATION forming part of Letters Patent No. 448,296, dated March17, 1891..

Application filed March 19, 1888. Serial No. 267,611. 1. (N model.)

To to whom, it may concern.-

Be it known that I, J OHN M. OURTIcE, a citizen of the United States,residing at Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful Improvement inYarn Guides and Clearers, of which the following is a specification.

Hy invention relates to yarn guides and clearers; and it consists in thedevices and combinations hereinafter described and claimed, which havefor their object the support of the supporting rail, securing the guidesand clearers in a proper position to said rail, and means of adjustingsaid guides and clearers and of preventing the same from getting out ofposition.

In the accompanying drawings, Figure 1 is a perspective view of ayarn-supporting rail, one of the supporting-posts, the upper part of thelifting-rod, and the yarn guides and clearers supported on said rail,Fig. 2, a front elevation of a guide and clearer and of a part of thesupporting-rail; Fig. 3, a rear elevation of the same; Fig. 4, avertical section on the line or a: in Fig. 2; Fig. 5, an isometric Viewof the clamp detached from the guide 5 Fig. 6, a front elevation of theupper part of a supporting-post and a part of the supporting-rail; Fi 7,a horizontal section on the line so as in Fi 6; Fig. 8, a side elevationof the upper part of said post and a cross-section of thesupporting-rail. In the remaining figures a modification of my inventionis represented, Fig. 9 being a plan of the same and a part of thesupporting-rail; Fig. 10, a front elevation; Fig. 11, a section on theline y yin Figs. 10 and 13; Fig. 12, a rear elevation of the same, andFig. 13 a vertical section on the line a z in Fig. 12.

A is a supporting-post supporting the supporting-rail B. Thesupporting-post A is secured in the usual manner by means of a collar aon the lower end of said post and a setscrew a, turning radially in saidcollar to the lifter-rod A, carried by the guiderail. (Not shown.) Mostcommonly the supporting-rail B is cylindrical, and is prevented fromturning in the supporting-post by a setscrew which passes into the frontof the post near the top of the same and thrusts against the rail, andsometimes the rail has aflat side to receive the thrust of said screw. Iflatten one side of the rail B atb for a different purpose. The posts Anear their upper ends are hollowed out at a to receive the convex partof said rail, and I secure to the post A, near the top of the same, aclamp-piece a by means of a screw a said clamp-piece being fiat on therear side and bearing against the flat side of the supporting-rail. Thisconstruction allows any post to be disengaged from the rail withoutdisengaging any other post therefrom, and allows the adjacent ends oftwo sections of the supporting-rail to be supported by one post. (Seedottedlines in Fig. 6.) Theclamppiece a is prevented fromturning by aver tical groove therein engaging a vertical rib a on the post. (SeeFig. 7.) The base 0 of the yarn guide and clearer is flat on its rearsurface, and is held against the flat side I) of the rail 13 by a clamp0, provided with an opening 0 to embrace the convex side of said rail B,said clamp being secured to the base 0 by a clamp-screw 0 which passesthrough a washer c" and through a vertical slot 0 into a tapped hole ain the lower part of said clamp, said vertical slot allowing the base ofthe yarn guide and clearer to be raised and lowered on thesupportingrail in an obvious manner.

To prevent the base 0 from turning on the supporting-rail, the upper endof the clamp c is provided with a tongue 0 which enters and fits avertical groove 0 in the back of the base 0, so that when theclamp-screw c is turned up the base and clamp cannot turn upon eachother.

The upper part of the base a is provided with a horizontal portion, overwhich the yarn is drawn in the operation of said guide and clearer, andthe yarn-kni to D is held parallel with the horizontal top of said baseby means of a shank or downward projection 11 on said knife entering avertical groove 0 in the base 0, the opening between the top of saidbase and the straight lower edge of the knife being adjustable by meansof a slot d, through which the holding-screw d is driven into said base.

The yarn is prevented from being drawn out from under the yarn-knife bya yarn-gateE of the construction shown in anotherapplication, Serial No.34,576, filed by me May 31, 1881, and now pending. Said yarn-gate E ispivoted at 6 within a recess 0 formed in the base c, and shown by dottedlines in Figs. 2 and 3, in such a manner that the weight of said gatecauses its pointed end e to be in contact at all times with the inclinedfree end of the knife D, except when a yarn is being introduced into theguide. A yarn-rest F of the form shown is secured to the base 0 in sucha manner as to almost conceal the yarn-gate and extends along parallelwith the front face of the base 0 at the upper edge of said yarn-rest,except at the ends of the yarn opening or space between the knife D andthe base 0, where it is carried upward at ff with a gradual curvature,as shown in Fig. 2 and described and claimed in said previousapplication. Between the points f f the yarnrest is rounded downward andfor-ward to present a large surface to the yarn to lessen the wear ofthe yarn thereon. The yarn-rest is secured to the base 0 by means ofrivets e f passing through an ear f with which said rest is provided,one 6 of said rivets serving as the pivot of the yarn-gate, and the saidear f forming a removable cap for the insertion of the yarn-gate. Theoperative portion of the yarn-rest is made very thin, so as to bechilled in castingand by its hardness to resist wear.

In the modified form of my invention shown in Figs. 9 to 13 the base ais clamped to the rod, as above described; but the clampscrew 0 alsoserves to hold the yarn-rest in proper position, said yarn-rest F beingprovided with a vertical shank f", having a vertical slot f throughwhich and through a vertical slot 0 in the base 0 as above described,said clamp-screw passes into the clamp 0, so that the base and theyarn-rest are adjustable in height with reference to the clamp, but notwith reference to each other, the lower end of the shank resting upon aledge or projection 0 east on the base, as shown in Fig. 13, and beingprevented from turning partly by said ledge and partly bya vertical ribc on the base and a vertical groove f in said yarn-rest. tends above theyarn-knife D along the entire upper edge of said knife and prevents theknife being accidentally struck and knocked downward in such a manner asto close or diminish the space between said knife and the yarn-clearingsurface of the base.

The yarn-knife D is adjustable vertically by means of a slot (1 in saidyarn-knife, through which the holding-screw d is driven into the base,and is guided by its vertical side or edge 62, resting against avertical shoulder c on the base 0 to keep the lower edge of saidyarn-knife parallel with the yarnclearing surface of said base.

The yarn-gate E is a finger pivoted at its upper end on a horizontalyarn-gate stud 0 The base o ex projecting from the base e f-against theback of the yarn-knife, so that the yarn-knife may be adjustedvertically without moving said gate. The yarn-gate E is longer than thedistance from its pivot to the yarn-clearing surface of the base, uponwhich surface thelower end of said finger rests, said finger standing inan inclined position with its lower end a little nearer the middle ofthe guide than its pivoted end, and its lower end on the inner side maybe provided with notches e to catch the yarn when an attempt is made bydoubling the yarn around the lower end of the finger to remove it fromthe guide.

I do not herein claim either the supportpiece (or base) having a chamberto receive the automatic stop-gate, in combination with the cap of saidchamber, having a yarn rest or supporter extended from said cap, or thecombination of such support-piece and yarnsupporter having inclines atits ends with an adj ust-able portion or yarn-knife, as thesecombinations are described and claimed in said application, Serial. No.34,576, above referred to.
